, SPECIFICATION forming part of Letters Patent No. 301,575, dated July 8, 1884.

Application filed March 22, 1884. (No model.)

To rtZZ whom 231; may concern..-

Be it known that I, FREDERICK J. DEVER- ALL, a citizen of the United States, and a residentof New York. in the county of New York and State of New York, have invented certain new and useful Improvements in Cans, of which the following is a. specification.

. The invention relates to an improvement in cans for fluids of all kinds.

The precise nature of the invention will appear from the detailed description hereinafter presented, reference being had to the accompanying drawings, in which Figure l is a sectional view of a portion of a can embodying the invention. Fig. 2 is a view, partly in section, of same. Fig. 3 is a similar view illustrating the pouring-spout turned into the can. Figs. 4, 5, and 6 are sootional views of modifications of the invention, and are hereinafter referred to.

In the drawings, A denotes the can, which may be of any desirable construction, having at its upper portion a mouth, B, encircled by the threaded flange G, adapted to receive the threaded cap D.

At the base of the flange G is provided an inwardly-projecting flange, LE), of sufficient width to receive and support 'the gasket F and air:

box G, through which projects th spout H, and which is subdivided into one or more airchambers, as hereinafter described. The cap G will depend somewhat upon the size of the is put together and inclose the diaphragms N- can and other-considerations; but it will be found that when the box is divided into three air-chambers, as will be hereinafter described, it will answer for cans of almost any descrip' tion.

The box G illustrated in Figs. 1 to 3 consists, externally, of the base L and top M, the vertical flanges of which meet when the box 0, each of which is provided with an aperture, I

G are held together by solder applied to thejoint formed by the meeting edges of the bottom and top, (lettered LM, respectively.) It is not essential that the diaphragms N 0 be soldered, unless they fit within the box very loosely; but when the top and bottom of the box are secured as above specified a portion of the solder will pass within the box and operateto attach the diaphragms N O to each other and to the parts L M. The apertures in the diaphragins N 0 will operate in combination with the vent K in the top of the box and the vent S in the bottom thereof, to permit the passage of air through the air chambers into the can. The vents in the box G will preferably be arranged as far as possible above the line of flow of the liquid, in order that when the can is tilted in the act of pouring oil therefrom the vents may be less likely to be interfered with by the entrance of the oil into the air-chambers. The box G has a smooth exterior, and is of suitable dimensions to be received within the flange O and cap D. The spoutH enters the box G about the center of its upper surface, and the spout being curved, its lower portion terminates at a point to one side of the center of the base of the box. When the device is in use, the box G will be arranged within the flange C, so that the lower end of the spoutH will be adjacent to the nearest side of the can, in which position it will be retained by placing the cap D over the box and screwing it down upon the flange 6. Vhen the can employing the invention is to be packed for shipment, or to prevent the evaporation and slopping of the fluid, the position of the box G will be reversed, the spout H being inserted into the can, after which the cap D will be applied, when the can will be ready for ship: nicnt. Upon the reversal of the position of the box G the oil will be prevented from escaping by reason of the fact that the gasket J will securely cover the base of the spout H and the vent S. The box G may have its position transposed at will, according to whether it is desired to pour oil from the can or to pack the same for shipment. NVhen the can is in use, the box G will be inserted with the spout H protruding upward therefrom, in the man ner shown in Fig. 1, when the oil may be allowed to flow therefrom without further-manipulation. The passage of the air into the various air-chambers effectually prevents any escape of the oil or other fluid through the vents. It is possible that a very small quantity of the oil may find its way into the lower air-chamber, and when used in connection with large oil-cans a drop of oil may pass into the second air-chamber; but my experience has demonstrated that no further escape of oil through the vents will occur.

The invention is one of great simplicity and is entirely effectual in its operation. When the can is packed for shipment, the spout is protected, and there is no projection upon the can which would be likely to be injured.

By means of the device whichis the subject of this application I am enabled to entirely dispense with the use of vents which are opened or closed by means of screws or other devices, and to produce a can which will be readily understood and cannot be easily injured by ordinary use.

The formation of the box G whereby the air-ohambers are produced may be modified in some respects without departing from the spirit of the invention, and in Fig. 4 I illustrate a modified form of valve, which consists of the top M and bottom L, inclosing diaphragms m n, which serve to form airchambers, and differ from the like devices illustrated in Fig. 1 only in details of construction. In this modified form of box G, however, the lower portion of the spoutH is not curved, but is expanded at its lower edge, and secured to the bottom of the box at about its center, the expanded portion of the spout being provided with apertures d. The'oil entering the spout to be discharged into the lamp or other receptacle first passes through apertures t, formed in the bottom L, and thence through the apertures cl into the spout H, through which it is permitted to escape. The employment of air-chambers in this embodiment of the invention is the same in every respect as that in the box G illustrated in Figs. 1 and 2, except that the airbox does not rest on the flange E, but on the top of flange 0. The diaphragmn is of leather in this embodiment of the invention, and a leather gasket, 8, is arranged between the outer edge of the tin diaphragm m and the lower edge of the top M, for the purpose of making a tight joint. The diaphragms ma are secured at their outer edges between the parts M L of the box G, and the part L is secured to the lower end of the spout H, while that lettered M is soldered around the aperture in its top to the spout. G shown in Fig. at is reversed in the manner indicated in Fig. 3, the gasket w prevents any escape of the oil through the apertures t.

In Figs. 5 and 6 I illustrate a formation of the air-box G which may-be successfully employed in cans in which the mouth is closed by a cap, D,which enters Within the threaded IVhen the box receiving-flange O. In this embodiment of the lower edge of the cap D. The spout extends through the air-box G, asshown, and is greatly strengthened therebya point of great importancein cans of the kind to which the air-box is applied. The air-box G shown in this connection has asingle air-chamber provided with vents, as it is intended for heavy lubricatingoils.

Whether the air-box G is made oval in vertical section, as shown in Figs. 5 and 6, or rectangular, as in Figs. 1, 2, and 3, a single airchamber therein may be made use of, since it is not essential in all cases that diaphragms subdividing the box be used.

\Vha-t I claim as my invention, and desire to secure by Letters Patent, is I 1. In combination with a can having a mouth, B, flange O, and cap D, open at its center, the spoutH, carrying upon its basetheair-box G, provided with vents, substantially as and for the purpose set forth.

2. In combination with a can having an opening, B, flange O, and cap D, open at its center, the reversible spout H and air-box G, which latter is provided with air-vents, and is subdivided into two or more chambers, substantially as and for the purposes set forth.

3. The reversible spout H and air-box G, which latter is provided with air-vents, and is subdivided by diaphragms N O, in combina 'tion with the can having at its mouth the re ceiving-flangeO and cap D, open at its center, substantially as and for the purpose set forth.

4:. The reversible spout H and air-box G, carried thereby, in combination with the can having a flanged mouth, and cap D, open at its center, the spout entering the air-box at its upper central portion and terminating at one side of its base, substantially as and for the purpose set forth.

Signed at New York, in the county of New York and State of New York, this 21st day of March, A. D. 1884.
